Another object of this invention is to pro-,

vide means for extinguishin the ignited wick when the apparatus is c osed so as to prevent oxidation of the casing immediately above the wick port-ion.

Another object of this invention is to provide means for protecting those parts of the walls of the lighter whlch are heated by p the wick from oxidation.

Another object of my invention is to provide a mechanism whereby certain of the parts can be manipulated or adjusted while the device is either in the operative or in the inc rative position.

Cllfher objects of this invention will appear in the following description and drawings which illustrate preferred embodiments of my invention. Flg. 1 is a perspective view of the fuel containing element and shows the closure therefor in open position. Fig. 2 is a lon itudinal section showing the opening an closing devices, the special wick cover and the special mounting for the ferrocerium element. Fig. 3 is a section similar to that shown in Fig. 2 but with the device shown in operative instead of in its inoperative position. Fig. 4 is a section of a device similar to that shown in Fig. 2 but embodying a modified form of cover or cap for the wick portion. Fig. 5 is a section taken on the line A-A of Fig. 4-. and showing a special construction for preventing oxidation of the walls of the lighter in the vicinity of the wick. Fig. '6 is a transverse section showing the holder for the ferro-cerium Igniting element, and the special means for revolving it about its longitudinal axis.

Referring to the several figures of the drawing, 1 designates a cartridge containing a fuel compartment 10, a wick 3 dip ing into said fuel compartment, and a hold er 4 for the. ferro-cerium element.' A friction element 9 is adapted to press against the ferrocerium igniter, said friction element bein rotated by means of the gear 22. A hinged cover 25 is provided for the wick and air holes 19 in the side walls'of the cartridge and situated at ap roximately the wick level,

are rovided for urnishing air to the wick.

T e cartridge 1, including all the elements contained therein and attached thereto, is adapted to fit telescopically into a shell 2, forming the assembly shown' in Figs. 2, 3, 4 and 5. A spring 8 is located between the end of the cartridge 1 and the inner portion of shell 2 and this spring 8 urges the cartridge 1 out of the shell 2. The outward movement of cartridge 1 is limited by a stop 17. Shell-2 and cartridge 1 have semi-circular recesses 30 and 31 formed in their upper portions so that when the two sections are moved ,into the position shown in Fig. 3, said recesses 30 and 31 are aligned and provide an opening through which the flame from the wick ma emerge. Shell 2 is provided with a reel; adapted to mesh at one side thereof with pinion 22.

The special construction for 'fillin the fuel compartment 10 in cartridge 1 is s own in Fig. 1. Referring to this figure, it will be seen that a hinged door or closure 18 is provided, which fits snugly into the end of the cartridge 1. For filling the fuel compartment it is only necessary to extract the cartridge 1 from the assembly in a manner which will be described later and to pour the fuel into the compartment 10 through the door 18. It will be noted from Figs. 2, 3

and 4 that when the cartridge 1 is in assembled position that spring 8 presses against the closure 18 and keeps it closed.

Means for insuring equal wear of the ferro-cerium element are shown in Fig. 6.

Referring to this figure, it will be seen that the igniting element has a square contour and that it is pressed upwardly by spring 51. This spring 51 is enclosed in a rotatable sleeve 52 and sleeve 52 fits into an outer shell 4 which is rigidly attached to cartridge pin 26 connecte 1. When the ferro-cerium igniting element becomes worn on one side it is only necessary to manipulate the element 11 to rotate sleeve 52 in shell 4 to expose a new portion of the igniting element. The inner surface sleeve 52 has a square cross-section at the point where it receives the pyrophoricalloy.

The special hinged cover for extinguishing the flame of the wick is shown in Figs. 2, 3 and 4. In the modification shown in igs. 2 and 3, the ca 25 is shown hinged to a to'the side walls of cartridge 1. A spring 27 is provided and this urges the cap 25 to turn upwardly on its pin 26. When the device is in the position shownin Fig. 3, it will be seen that the cap 25 swin s clear of the cartridge 1 and the shell 2. hen .the device moves into the position shown in Fig. 2, the movement of cartridge 1 in shell 2 forces the cap 25 back to enclose the wick. A lug 28 of sufficient length is provided on cap 25 to force the cap 25 down so that it fitssnugly onto the wick.

In the modification shown in Fig. 4, the cap 25 is hinged at 26' and it is raised from thewick when the shell 2 is pressed against the pin 29, the horizontal movement of the pin producing an upward turning motion of the cap 25 by means of the lever 32 and the hinge 26'. The cap 25- is brought back to its closed position by means of the spring 33 which urges the pin 29 to the ri ht.

Figures 4 and 5 show the improve means provlded for preventing oxidation of the walls of the lighter adjacent the wick. Referring to these figures, it will be seen that a U shaped piece of sheet metal 60 is provided which fits snugly between the upcuate opening 61 per walls of cartridge 1, and is interposed between the wick and the lateral walls of the cartridge. The legs of the piece of metal 60 .U' are curved inwardly (see Fig. 5) and they are stamped out to provide an arfor theflame'enters through the holes 19 in the walls of the cartridge 1, and it passes to the wick through the openings 61 and it.

i "also ascends (see Fig. 5) through passages 62 forined by the concave. portions of protecting element and the permanent walls' of the cartridge 1. The air ascending through passages 62 serves to cool the protecting element 60 and also serves to prevent the transmission of heat from the protecting element to the walls of the cartridge. When the protecting element becomes oxidized it can-be slipped out and a new one may be introduced.

The mode of operating the device will now be described. Assummg the lighter to be in the inoperative position shown in Fig. 2, cartridge'l is premed so as to move into shell 2-against the action of spring 8. As

. cartridge 1 moves. inwardly, rack 40- rotates (see Fig. 4). The air.

with air inlets,

shell 2. Air for the flame is thus provided and an outlet for the flame is also provided. As the orifices 30 and 31 begin to come into alignment, the opening at the to of the lighter is gradually uncovered and cap 25 or 25) under the action of the spring 27 or in the modification shown in Fig. 4 under the action of pin 29) swings clear 0 the wick. Since the uncapping of the wick begins as soon as the cartridge 1 is forced into its shell 2, there is ample time for the s arking element to ignite the wick. The

ame thus produced rises between the protecting walls of the element 60 and emerges through the opening in the top of the lighter. When the pyrophoric alloy becomes used on one side, element 11 is rotated to provide a fresh surface. To extinguish the lighter it is only necessary to release the pressure on cartridge 1. The sprin 8 then moves the cartridge out of the shel 2 until the stop 17 prevents further movement of the cartridge causing ,the capping to fit onto the wick and to extinguish the flame. The various elements then assume the positions shown in Fig. 2.

When it is necessar to refill the fuel compartment, stop 17, w at a small angle from the plate 16 (see Fig. 1) is forced inwardly while the apparatus is in the position shown in Figs. 2 or 4.

separated and the refilling operation may be erformed. The plate 16 is secured to the dy cartridge 1, by a small rivet 80.

It is to be understood that the invention is not limited tow the particular constructional embodiments which have been more particularly described but that all modifications are included falling within a fair interpretation of the claims;
